Shifting Reactions B Question 12

Experiment #1:
The first RICE table for the reaction shows the final amounts of R, BG, RG and B:

Reaction	R	+BG		RG	+B
Initial	0.600	0.700		0.800	0.900
Change
End	0.430	0.530		0.970	1.070

The second RICE table for the reaction shows the change amounts of BG, R, RG and B:

Reaction	R	+BG		RG	+B
Initial	0.600	0.700		0.800	0.900
Change	-0.170	-0.170		+0.170	+0.170
End	0.430	0.530		0.970	1.070

Notice the pattern in the Change row of the ICE table.
